On May 9, 1917, the company became the Boeing Airplane Company. In late 1917, the U.S. entered World War I and Boeing knew that the U.S. Navy needed seaplanes for training. So Boeing shipped two new Model Cs to Pensacola, Florida where the planes were flown for the Navy.
At the end of the war, Boeing began to concentrate on commercial aircraft, secured contracts to supply airmail service and built a successful airmail operation and later passenger service that evolved into United Airlines.
